'I am outraged that I have missed my bus home, thanks to YOU lot!'

The Manager
'How did this happen sir?'

Stupid Customer
'I wanted this wine because it was special offer, however when I went to the check out, the wine wouldn't go through as the deal. Now I have missed my bus home... I am absolutely livid!'
